Bond, I've recently noticed these problems in the source also. Not the flak one (my game has not yet gotten to the point where I'm putting in explosives) but the blood decals and such. I didn't notice the enemy one, but it might have been there. I haven't fiddled much with the source since I upgraded DBP, and I have to say the 5.9 source seemed to work alot better. I did alot of changes to it, and lost them all when I started with the U62 source. Unfourtunetly, while my changes are simple (although time consuming sometimes) to implant, I have not bothered due to the reasons you have mentioned.
Please tell us what TGC says if and when they reply to your problem.
Speaking of timers though, with DBP 5.9 I had also looked into a timer system - except mine was planned to be entity specific, so they wouldn't and couldn't share timers. I did plan to still have a global timer though. If you want to try it it would involve timers setup in each entity, probally by editing their primary array.
Due to the size of the source and the 6.0 upgrade however I never got around to implanting this, and once the U62 source came out it was the first thing I set out to do. I haven't finished it (and the bugs make me feel it isn't yet worth it) so it's nice to see someone is at least trying and doing well with it. Your mod and the flashlight one are both the only released FPSC source mods that I've seen so far. When the code was first released for 5.9 I thought everyone would try and do what they wanted with it. Of course, I also expected it to be a bit more orginized
While you wait for a reply from TGC I'll tell you if I find any solutions to these problems. I've been with DBP for a long time now and beleive I can at least fix some of it. The bullet holes, however, either require re-formatting the image or re-doing DBP's "add scortch" command.
Alright, now that I've rambled on almost as much as Uman does, I think I can press the post button
That and my laptop battery is about to die
